Leucocoryne plant named ‘Paulina’

ABSTRACT

A new and distinct cultivar of  Leucocoryne  plant named ‘Paulina’ characterized by having: green, white and violet lightly obovate tepals and red-purple lines across them; yellow-green staminodes; and a pleasant aroma.

Latin name of the genus and species of the plant claimed: Leucocoryne species.

Variety denomination: ‘Paulina’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of the Leucocoryne plant, known in Chile as Huilli and botanically known as Leucocoryne(species unknown). The new cultivar is referred to herein by the cultivar name ‘Paulina.’ Leucocoryne are bulbous herbs that are native to Chile.

The new cultivar was selected from a population grown in a cultivated area (greenhouse) in Chile in 1998, by the inventors, Levi Mansur Vergara and Gabriela Verdugo Ramírez. The population from which the instant cultivar was selected originated from uncontrolled crosses among unknown Leucocoryne plants. Asexual propagation has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar was first asexually reproduced in a cultivated area (greenhouse), in Chile in 1999. The method used to asexually reproduce was natural bulbification. The new cultivar reproduces true-to-type.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Paulina’ which in combination distinguish this Leucocoryne as a new and distinct cultivar:

-   -   1. Tepal shape: lightly obovate;     -   2. Tepal color: Base green, RHS 134 A; middle portion white;         violet apex, RHS N87 D, and red-purple line across the tepal,         RHS N74 A (both surfaces).     -   3. Aroma: pleasant; and     -   4. Staminode color: Green-yellow 1 C.

‘Paulina’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar, with the exception of flower design as shown in the second drawing sheet, may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant. However, the phenotype is reproduced true-to-type under the environmental conditions in which they were observed. The following observations, measurements and values describe the new cultivar as grown in Quillota, Chile (32° 53′ lat. S; 71° 16′ long. W) under conditions that favor normal Leucocoryne growth.

BRIEF DESCRIPTION OF THE DRAWING

There are three accompanying drawings that illustrate the overall appearance of the new Leucocoryne cultivar ‘Paulina’. These show the umbel, the flower, and the foliage of ‘Paulina’. The images portray colors as true as is reasonably possible with colored reproductions of this type.

The first photographic drawing shows the umbel of ‘Paulina’, depicting a cluster of inflorescences and buds.

The second photographic drawing shows a close-up of the flower of ‘Paulina’ and the third photographic drawing shows the foliage of an adult plant of ‘Paulina’.

DETAILED BOTANICAL DESCRIPTION

The following observations, measurements and values describe the new cultivar as grown in Quillota, Chile (32° 53′ lat. S; 71° 16′ long. W) under conditions that favor normal Leucocoryne growth. Leucocoryne cultivar ‘Paulina’ has been grown in unheated greenhouses from March to November, under a temperature regime as described in Table 1 below:
